Grey table background not visible

Hey, I use Adobe Acrobat XI Pro and I have a little issue.

A supplier provide us with datasheet in PDF (just to say I don't have acces to original document).

When I open it with my AAXI Pro, it doesn't show the grey background in table.

It work perfectly on my colleague Adobe or on other application.

I guess it is a parameter issue but I can't find it ... Tried almost everything in display and color management (I just translated the tab name, might not be accurate).

Here is how it look in my AA  (left) and how it should look (right ; screen from another application) :

Thans for your help.
